 Check ur connection string properly and check if server is alive and listening at port 1443 (i guess u may set this port for sql server connection) on ur server side. Check whether at server side u r able to connect to server with given username and password and if all is Ok then we may have digg for possible solution.
  post comment on ur problem further.


ThankU

how "slow"?

if it's like 30 seconds, you must check if the dns resolution for the server name is slow eventually.
-> try to use the server's IP address instead of the name and see if that helps. if it does, check with the fully qualified server name (fas_1.). disuss the results with your network administrator

if that does not help, it's either:
* the network itself being swamped with traffic -> to be discussed with the network admin
* the server being slow to respond, due to high traffic or general slowness -> check while logged in the server itself, if the machine is sluggish or not?

what kind of timeout are you talking out
connection timeout - means that you are getting this error after 30 seconds while trying to connect to the sql server, if you set this value to 0 then its infinite (not recommended)

command timeout - means that the connection has been established but you query execution is talking longer than the default time or 30 seconds and timing out
you can set the command timeout to 0 means infinite by default its 30 seconds

Does SQL Server on your development machine accept TCP connections? You may find that the service is listening only on Name Pipes & Shared Memory.

the author is not using an ip to connect to the sql server machine so it does not matter if tcp is enabled or not

Oops, just finished working on a MySql system, and they use Server to specify the host.

Hi,
Ok today it has not timed out today and i changed the server name to its IP address and still quite slow
I am connecting to a dev server and tested the connection speed and its averaged to 6 seconds
 
thanks

if you used the ip address, and it's still slow, then it's not the dns server resolution.

please check the server itself, how is it's memory and cpu utilization?

Hi,
@ragi0017 - as far as i know they r on the same lan and sub net mask. I am on site so i will have to confirm that with the System Aministrator - they have plugged my notebook onto the domain, however i am not logging onto the Active directory as an autehnticated user, could that perhaps be the problem?
 
thanks
